2. (30%) Suppose we have a processor with a base CPI of 1.0, assuming all reference hit in the primary cache, and a clock rate of 5GHz. Assume a main memory access time of 100 ns, including all the miss handling. Suppose the miss rate per instruction at the primary cache is 2%.

2.1 (10%) What is the CPI if this single-core processor only has one level of cache?
